'Constant Counting' printed from http://nrich.maths.org/

Skip counting or counting by the same number each time is ways
to describe constant counting. This is what happens when you recite
the multiplication tables. Work partners Joanne and Holly, and Steve and Matt from Moorefield Junior School,
found that to reach 24 they could count by skipping 1s, 2s, 3s, 4s,
6s, 8s, 12s or 24s to reach 24, the target number. 24 is an answer
in each one of those multiplication tables.

David, who is
studying at De Aston School, gives us this example:

24 = 1 x 24
24 = 2 x 12
24 = 3 x 8
24 = 4 x 6

Several people did not mention counting by one or by two;
perhaps they thought that was too obvious. Others found some of the
different ways to skip count to reach 24 but did not list all of
the possible ways.
